一、热的产生 精冲是处于三向受力状态。整个冲我过程是在高温和高压下进行的。 热的产生,是由于冲裁功在冲裁过程中转化为热。也就是说,在瞬时冲击载荷的作用下,剪切区内金属晶体发生强烈的位错(见图1),而达到激发温度。 二、温度场 温度场——是指精冲时,凸、凹模之间材料变形区的热影响范围。 First, the heat generated fine blanking is in a state of three-force. The whole process of red me is carried out under high temperature and pressure. Heat is generated due to the punching work in the blanking process into heat. That is to say, under the instantaneous impact load, the metal crystal in the shear zone is strongly dislocated (see Figure 1) and the excitation temperature is reached. Second, the temperature field Temperature field - refers to the fine blanking, convex, die material deformation between the heat affected zone.
